Oh, boy: Another hot summer day, another list of top vehicles for a road trip. Whereas Kelley Blue Book's top road trip cars list — the last such list we had to endure — was one of the more strange groupings we've seen, today's list from Automobile is absolutely sexy. What, you don't think the Sprinter's sexy? You ever seen the Mercedes diesel it's got under the hood? We're not kidding when we say it's like butter. Really thick, viscous, black butter, but butter nonetheless. Hit the jump for the full list.
